Daily AI RoundupsFriday, 24 July 2026

The 24 Jul 2026 Calathea roundup leads with WSJ reporting that Stripe is in talks to acquire OpenRouter for around $10 billion, followed by Black Forest Labs putting FLUX 3 Video and Action into early access and Etched raising $300 million at a $10.3 billion valuation. Microsoft is replacing OpenAI image models in PowerPoint and Bing with its own MAI models. The edition also covers Bad Theory Labs' BTL-3 coding-agent adapter, a Möbius RoPE retrieval preprint, Hetzner's experimental managed inference API, arguments about routing and model learning from Kun Chen and Lee Robinson, Anthropic's Economic Index connector for Claude, Max Woolf's Jacobian Conjecture test across 14 LLMs, Moonshot AI's reported access to Nvidia GB300 chips, AMD's Helios production update and Ethan Mollick's guide to supervising AI agents.
